PURPOSE
As new features are about to land in survey, notably live interactions [1]
and new survey building [2] performing a pre cleaning is necessary. In this
PR we clean survey models by: removing unnecessary fields, cleaning some code
and finally renaming models.
SPECIFICATIONS
``question_ids`` field name is quite difficult to understand as we wonder why
there is such a field on user input model. As its purpose is to store questions
user has to answer (randomly chosen or all chosen) let us rename it to
``predefined_question_ids``.
Moreover starting from now on if it is now given at create it is automatically
computed. Classic flows go through ``survey._create_answer()`` method that
prepares them accordingly. However tests or demo data do not necessarily go
through that method and it makes scoring fail (notably) if people forget
to define them.
Let us automatically generate them at user input create if not given.

Purpose
=======
The "page" concept is now only present in the user interface.
Surveys are split in "sections" that have two purposes:
- Organizing a (long) survey/certification
- Allow to pick a random questions count for that section (more information here after)
On the user interface, based on the questions_layout field, surveys are displayed:
- On a single page, where sections still appear but are only used as visual separations
- On multiple pages, having one page per section (this matches the previous behavior)
- On multiple pages, having one page per *question*
On top of that page concept, this commit added randomization for the survey questions.
The randomization mechanism will take X questions per section of the survey.
The survey.user_input is initialized with the selected questions to be sure to keep that
set of questions and avoid showing a new set of questions every time the user refreshes the page.
This also allows to easilly go back and know which question we have to show.
